"Payback" is a mission in the game Grand Theft Auto IV involving the elimination of several Pavanos members.

1. When the Pavanos crash into the car dealership, use grenades or the rocket launcher to blow up nearby cars
2. Clear out quick because the cops will be attracted by the explosions

Get in a good car and drive to the diner. You'll see two of the Pavanos' meeting. One spots you and tells the other to lose you in a car chase. Drive the car, following as closely as possible. Track him to an auto repair shop. The Pavanos' begin shooting. Blow up the two cars with a rocket launcher, killing everyone in the area. If cops appear, escape from them. Then return to kill the remaining Pavanos' and end the mission.
